Hydrogen Breakthrough Could Open the Road to Carbon-Free Cars

Here’s good news on the hydrogen storage front. UK scientists have developed a compound of the element lithium that may make it practical for hydrogen fuel cell cars to drive more than 300 miles before refuelling. Fuel cells produce carbon-free electricity by harnessing electrochemical reactions between hydrogen and oxygen. Today’s prototype HFC cars have a range of only 200 miles, and a 300-mile range would require storage the size of a double-decker bus.

But the UK research has focused on a different approach enabling hydrogen to be stored at a much higher density within acceptable weight limits. The option involves a well-established process called ‘chemisorption’, in which atoms of a gas are absorbed into the crystal structure of a solid-state material and then released when needed. This could tip the balance in favor of a truly marketable technology.

Fuel-cell technology could assist the emergence of a hydrogen economy rather than a carbon economy. A 2004 report concluded that hydrogen vehicles alone would enable the UK to meet its Kyoto targets for CO2 reductions.

Let’s hope this technology gets on the road fast. –JULIA WHITTY

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily crazy—Mother Jones' journalism is driven by one simple question: Will America will move closer to, or further from, justice and equity in the years to come?

If you're able to, please join us in this mission with a donation today. Our reporting right now is focused on voting rights and election security, corruption, disinformation, racial and gender equity, and the climate crisis. We can’t do it without the support of readers like you, and we need to give it everything we've got between now and November. Thank you.
